Quantitative vibration perception thresholds in normal and diabetic chinese: influence of age, height and body mass index.

In this study, we established normality data of vibration perception thresholds (VPT) in a Chinese population. Over 1,400 healthy subjects were recruited to create age-related centile charts of VPT after pretesting for reliability. Another 273 diabetic (DM) patients were recruited to assess the impact of age, height and body mass index (BMI) on VPT values in DM and non-DM subjects. The present study is the first one which reports normality data of VPT from a large Chinese population. The VPT values were higher in male and female DM patients than in the non-DM counterparts. Age significantly contributed to the variance of VPT in both DM and non-DM subjects. Height was positively associated with VPT in men, so was BMI in non-DM subjects with much smaller magnitudes of effect than for age. Copyright 2002 S. Karger AG, Basel
